RECENTLY DISCOVERED FUNGI IN YORKSHIRE.— V. 



WITH NOTES ON NEW AND RARE SPECIES. 



C. CROSSLAND, 

 Halifax. 



The following catalogue of Fungi newly discovered in York- 

 shire demonstrates that mycological field work in our county 

 is far from being played out, and that a continuation of this 

 kind of work is called for. 



All the 64 species included were, with two or three excep- 

 tions, found last year. Many have already been temporarily 

 mentioned in ' The Naturalist,' but by bare name only. It 

 will be seen that two are new to Science, and eleven new to 

 Britain. A few others are in hand, concerning which some 

 little doubt exists ; these are awaiting fresh and more abundant 

 material for further consideration. 



This is the fifth series of additions since the publication of 

 the ' Yorkshire Fungus Flora,' bringing the total of Yorkshire- 

 fovmd species to 2895 or thereabouts ; in other words, 269 have 

 been added during the intervening six years. 



The words ' To precede ' and ' To follow,' accompanied 

 by a number, attached to each new record, denote the position 

 they should occupy in the sequence of species followed in the 

 Flora. 



It is thought necessary to add a few corrections at the 

 close concerning other species previously recorded. 



NEW SPECIES. 



Pluteolus mulgravensis Mass. and Crossl. 



Pileus somewhat fleshy, convex then expanded and unibonate, 

 flocculose, becoming broken up into squamiiles, striate, grey, 

 5-6 cm. across ; gills free, crowded, white then cinnamon, broad ; 

 stem stuffed, smooth, almost equal, base somewhat clavatc, ichitish. 

 4 cm. long; spores elliptical, ochraceous-brown, 9-10x4-5 /'. 



N.E. — On wood, Mulgrave ^^'oods. (F.F.. Sep. 1911, ' Nat.', 

 Nov., pp. 387-393)- [To follow 394]. 



Structurally Pluteolus agrees with Pluteus, differing in 

 having brown instead of pink spores. P. mulgravensis differs 

 from the two previously known European species, P. reticulatus 

 and P. aleuriatus, in the umbonate, striate cap becoming 

 squamulose, and in the larger spores. The last-named species 

 was also collected during the Foray. 



Pileus carnosulus e convexo expanso uniboiiatus flocculosus, 

 dein squamuloso-diffr actus, striatus, griseus, 5-6 cm. latus. 

 LamellcB liberce, confertce, ex albo cinnamomcB latce. Stipes 

 farctus, glaber, siibcequalis, basi subclavata, albidus, 4 cm. longus, 

 3 mm. crassus. SporcB ellipsoida, ochraceo-brunnece , 9 10 X
